I've been doing some live streaming lately, and learned that Adobe's Flash Media Live Encoder is cross-platform. Unfortunately, it's been ludicrously unstable crashing occasionally during use, and always crashing when told to quit.

After searching for alternatives, the closest I came was Telestream's Wirecast product, which despite it's "affordable" claim, is $450 I don't have, and about $400 worth of features I don't need.

What I need in a rtmp/flash streaming client is:

Stability and a good native feeling client. Adobe's dark-grey drab interface is neither of these things.

Support for XML profile import. I'm unsure of any other specific term for this, but Nico Nico has a link in their streaming interface to download an XML file containing stream quality parameters, default device selection, and of course the URL of the streaming server. It's wonderful to simply tell FMLE to open this file, and then just click 'Start'.

I have no specific requirements of 'effects' or generally ways to change the stream. I use CamTwist as a front-end device to set the video however I want.

By which I mean, all of Influxis' apps are free, but there aren't download links, which makes me believe I have to signup and pay for their services first.

Yes you have to pay something, it's not much though if you want to see something running. But why don't you get Adobe FMS development license and you'll get some examples as well?

Using FMLE 2.3 under OS X 10.7 on my MacBook Pro. - I didn't state that FMLE doesn't support XML profiles, I said that if I use some other app, it must support XML profiles. - The settings are all provided by Nico Nico, which means that I don't control the settings, nor can I optimize anything server side.
